As I mentioned in a previous entry, today’s New York Post reported that Broadwell ended the affair in September 2011, and that Petraeus kept sending her e-mails. (By the way, how could anyone be so stupid as to send self-incriminating messages via e-mail?) But the Washington Post has a very different-sounding story, in which it was Broadwell’s aggressive behavior which led to the discovery of the affair:

The collapse of the impressive career of CIA Director David H. Petraeus was triggered when a woman with whom he was having an affair sent threatening e-mails to another woman close to him, according to three senior law enforcement officials with knowledge of the episode.

The recipient of the e-mails was so frightened that she went to the FBI for protection and help tracking down the sender, according to the officials. The FBI investigation traced the threats to Paula Broadwell, a former military officer and a Petraeus biographer, and uncovered explicit e-mails between Broadwell and Petraeus, the officials said.

When Petraeus’s name surfaced, FBI investigators were concerned that the CIA director’s personal e-mail account had been hacked and that national security had been threatened. The officials said further investigation, including FBI interviews with Broadwell and Petraeus, led to the discovery that the two were engaged in an affair.

The identity of the woman who received the e-mails was not disclosed, and the nature of her relationship with Petraeus is unknown. The officials said the woman did not work at the CIA and was not Petraeus’s wife, Holly. The law enforcement officials said the e-mails indicated that Broadwell perceived the other woman as a threat to her relationship with Petraeus.
